  1. For the Napoleon of Tuna:
  2. Center a rack in the oven and preheat the oven to 325°F
  3. Stack the slices of bread and trim off the crusts. Cut the square bread stack into 2 even rectangular ones
  4. Place the 12 pieces of bread in a single layer on a baking sheet with a rack or another pan on top to prevent them from curling when drying. Bake them in the oven for 6 to 8 minutes or until golden
  5. Remove from heat and set aside to cool Carefully rub each dried toast with the garlic clove and discard the garlic or chop the clove and add it to the vegetable salad
  6. With a sharp knife, cut the cold tuna at an angle into 12 thin slices 1/4 inch thick, about the size of the toast. Place the tuna slices on a plate and season them with the lemon juice, olive oil, chives, and salt and pepper
  7. Place a slice of tuna on each slice of toast and then assemble these to make 4 napoleons of 6 layers each (three toast, three tuna)
  8. Presentation

  12. Drizzle the sandwich and plate with the remaining 1 tablespoon of olive oil and remaining lemon juice
  13. Serve immediately so that the toast remains very crisp
